Description

Technical Field

[0001] The invention belongs to the technical field of optics and relates to a color aperture generating device. Background Art

[0002] Full-spectrum white light can produce light of different colors after dispersion, and based on this principle, colorful lighting effects can be obtained.

[0003] For example, Chinese invention patent application number 99231546.8 discloses a new type of colored spotlight that utilizes the dispersion phenomenon. A mixed-color light source is mounted on a light-shielding reflector (parabola) or the focal point (line) of a lens. After reflection from the light-shielding reflector or transmission through the lens, the light becomes nearly parallel. This parallel light passes through a dispersion prism along its vertical cross-section, resulting in a colored light band. If the dispersion prism is strip-shaped, the colored light band is strip-shaped; if the dispersion prism is annular, the colored light band is annular.

[0004] The above-mentioned spotlight can only produce a circle of colored light, but this colored light only has one circle, and cannot produce the effect of more than one circle of colored apertures arranged in concentric circles. Therefore, the existing device cannot achieve the light effect of at least two circles of colored apertures. Summary of the Invention

DETAILED DESCRIPTION

[0035] The following are specific embodiments of the present invention and the accompanying drawings to further describe the technical solutions of the present invention, but the present invention is not limited to these embodiments.

[0036] like Figure 1、 Figure 2 As shown, a color aperture generating device includes: a light-emitting unit, a light-shielding film 200, and at least two groups of dispersion elements. The light emitted by the light-emitting unit forms at least two rings of light after passing through the light-shielding film 200, and these rings of light are dispersed by the dispersion elements to form at least two rings of color apertures 900. Each color aperture 900 contains at least two or more colors of circular light, and two adjacent color apertures 900 are set as an inner aperture and an outer aperture, and the inner aperture is located inside the outer aperture. Figure 9 As shown, in the actual structure, these color apertures 900 are distributed in concentric circles.

[0037] like Figure 1 、 Figure 2 As shown, the light-emitting unit can emit light. Specifically, the light-emitting unit is configured as a full-spectrum LED lamp 110 that can generate white light, and the full-spectrum LED lamp 110 is arranged on a circuit board. Since the white light emitted by the full-spectrum LED lamp 110 is composite light, it can form a variety of monochromatic lights after dispersion, so it can form colorful light.

[0038] like Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 、 Figure 5 As shown, the shading film 200 is configured as a light-proof structure, which has at least two groups of annular light-transmitting portions that can transmit light. The shading film 200 blocks the path of the light emitted by the light-emitting unit, that is, the shading film 200 blocks the front of the light-emitting unit, so that the light emitted by the light-emitting unit passes through at least two groups of the annular light-transmitting portions to form at least two circles of non-overlapping annular light (that is, an annular white aperture structure).

[0039] The shading film 200 can generate annular light. Since the color aperture 900 is a circular light effect, the annular light can be dispersed to obtain annular colored light. The relative positions of each group of annular light-transmitting parts can be set according to the required distribution structure of the colored light.

[0040] On the basis of the above embodiment, if the full-spectrum LED lamp 110 is a point light source, the light it generates is non-parallel light, which is not conducive to the formation of annular light by the shading film 200, and the brightness of the generated annular light is low, so a line light source generator 700 for forming parallel light is provided between the full-spectrum LED lamp 110 and the shading film 200. The line light source generator 700 can be set to a hollow conical lens structure or other structure that can refract light into parallel light, which can refract the white light emitted by the full-spectrum LED lamp 110 into parallel light toward the shading film 200.

[0041] Preferably, in an actual structure, the light shielding film 200 is attached to the end surface of the line light source generator 700 , so the parallel light emitted from the line light source generator 700 directly forms at least two circles of annular light.

[0042] like Figure 1-8 As shown, there are at least two groups of dispersion elements, and each group of dispersion elements is arranged in a one-to-one correspondence with each group of annular light-transmitting portions. Each group of dispersion elements is located on the path of the annular light generated by each group of annular light-transmitting portions, so that at least two circles of annular light are dispersed by each group of dispersion elements to form at least two circles of non-overlapping colored apertures 900.

[0043] It should be noted that, since the dispersion element and the annular light-transmitting portion are provided in at least two groups, two or more circles of color apertures 900 can be formed, and the greater the number of apertures, the larger the entire device.

[0044] In an actual structure, each group of annular light-transmitting portions can be arranged as a concentric circle structure, and each group of dispersion elements can be arranged concentrically, so that the effect of multiple color apertures 900 arranged in concentric circles can be obtained.

[0045] like Figure 1 、 Figure 2 、 Figure 6 、 Figure 7 As shown, the number of the dispersion elements is set to two groups, and the two groups of dispersion elements are respectively a first lens 410 and a second lens 420. The first lens 410 and the second lens 420 can disperse two annular light rays respectively to form two color apertures 900, wherein the first lens 410 and the second lens 420 are both set to annular prisms, which can disperse annular white light to form a color aperture 900.

[0046] The annular light-transmitting portions are provided in two groups, and the two groups of annular light-transmitting portions are a first light-transmitting ring 310 and a second light-transmitting ring 320. The first lens 410 is aligned with the first light-transmitting ring 310, and the second lens 420 is aligned with the second light-transmitting ring 320. Structurally, the light-shielding film 200 is located directly in front of the full-spectrum LED lamp 110 (here, the light irradiation direction is assumed to be forward), while the first lens 410 is located directly in front of the first light-transmitting ring 310, and the second lens 420 is located directly in front of the second light-transmitting ring 320. As a result, the first lens 410 and the second lens 420 act on two annular light beams, respectively.

[0047] It should be added that, based on this structure, additional light-transmitting rings and additional lenses can be provided according to actual needs, thereby forming three, four or more color apertures 900. However, no matter how many color apertures 900 are generated, the above-mentioned structural foundation for generating two color apertures 900 is necessarily required. Therefore, continuing to add light-transmitting rings and lenses on the basis of the above-mentioned structure will inevitably fall within the protection scope of this embodiment.

[0048] like Figure 1 、 Figure 2 、 Figure 6 As shown, in order to prevent the first lens 410 and the second lens 420 from interfering with each other, a light shielding ring 500 is provided between the first lens 410 and the second lens 420 (i.e., a light shielding ring 500 is provided between adjacent dispersion elements). The first lens 410 is located within the light shielding ring 500. The light shielding ring 500 can separate the first lens 410 and the second lens 420, thereby preventing interference between the two annular light rays during dispersion.

[0049] like Figure 1-8 As shown, in order to allow the two circles of colored aperture 900 to be distributed in inner and outer circles, the first light-transmitting ring 310 can be located inside the second light-transmitting ring 320, so that one ring-shaped light can be located inside another ring-shaped light. Since the first lens 410 and the second lens 420 are annular prism structures, the first lens 410 is located inside the second lens 420. In this way, the two ring-shaped light rays forming the inner and outer circle distribution can pass through the first lens 410 and the second lens 420 respectively. The two colored apertures 900 formed by dispersion can form an inner and outer circle distribution, that is, one colored aperture 900 is located inside the other colored aperture 900.

[0050] In the actual structure, the two colored apertures 900 are distributed in concentric circles. In order to achieve the above effect, the first light-transmitting ring 310 and the second light-transmitting ring 320 are concentrically arranged, so the two ring-shaped light rays are also distributed in concentric circles. The first lens 410 and the second lens 420 are concentrically arranged, so that the two circles of colored apertures 900 are one inside and one outside and form a concentric circle distribution.

[0051] like Figure 1-5 As shown, an annular reflective film 600 is also included, and the annular reflective film 600 is located on the path of the colored light emitted by the first lens 410. Since the colored aperture 900 emitted by the first lens 410 is located within the colored aperture 900 emitted by the second lens 420, the annular reflective film 600 is required to reflect the colored aperture 900 emitted by the first lens 410, thereby adjusting the position of the colored aperture 900.

[0052] like Figure 1 、 Figure 2As shown, it also includes an outer shell 810, an inner shell 820, an upper cover 830 and a back cover 840. The inner shell 820 and the back cover 840 respectively cover the two ends of the outer shell 810. The annular reflective film 600 is connected to the inner shell 820. The upper cover 830 covers the inner shell 820. The light-emitting unit, the shading film 200, the dispersion element and the inner shell 820 are arranged in sequence in the outer shell 810 along the direction of light emission.

[0053] The inner shell 820 has a through hole, the upper cover 830 covers the inner shell 820, and the annular reflective film 600 is arranged on the hole wall of the through hole. During actual operation, the colored light formed by the dispersion of the first lens 410 is emitted toward the annular reflective film 600 and reflected toward the upper cover 830. The colored light formed by the dispersion of the second lens 420 passes through the through hole of the inner shell 820 and is emitted to the upper cover 830.

[0054] The light-emitting unit can emit light toward the upper cover 830. After passing through the line light source generator 700, the white light forms parallel light toward the shading film 200, and after passing through the shading film 200, at least two annular light rays distributed in concentric circles are formed. Each annular light ray is emitted to a group of corresponding dispersion elements, and after passing through the dispersion elements, a circle of colored aperture 900 is formed. Therefore, the device can generate at least two concentric colored apertures 900, and all colored apertures 900 can be presented at the upper cover 830.

[0055] It should be noted that all directional indications in the embodiments of the present invention (such as up, down, left, right, front, back, etc.) are only used to explain the relative position relationship, movement status, etc. between the various components under a certain specific posture (as shown in the accompanying drawings). If the specific posture changes, the directional indication will also change accordingly.

[0056] In addition, in the present invention, descriptions such as "first," "second," and "one" are for descriptive purposes only and should not be understood to indicate or imply their relative importance or implicitly specify the number of the technical features indicated. Therefore, a feature specified as "first" or "second" may explicitly or implicitly include at least one of such features. In the description of the present invention, "plurality" means at least two, such as two, three, etc., unless otherwise specifically defined.

[0057] In the present invention, unless otherwise specified or limited, the terms "connection" and "fixation" should be understood in a broad sense. For example, "fixation" can mean fixed connection, detachable connection, or integration; mechanical connection or electrical connection; direct connection or indirect connection through an intermediate medium; internal communication between two elements or interaction between two elements, unless otherwise specified. Those skilled in the art will be able to understand the specific meanings of the above terms in the present invention based on specific circumstances.

[0058] In addition, the technical solutions between the various embodiments of the present invention can be combined with each other, but it must be based on the fact that ordinary technicians in this field can implement it. When the combination of technical solutions is mutually contradictory or cannot be implemented, it should be deemed that such a combination of technical solutions does not exist and is not within the scope of protection required by the present invention.
